The Japanese version ("Ohgon no Siro") and the prototype ("Golden Castle") have a nudity feature not present in Gladiator. The female warrior Irene is shown with bare breasts when defeated by removing all layers of her chest armor (In Gladiator she still wears a bikini top when defeated this way).

When Gurianos is fully armored, the player may create a momentary protective shield by rapidly moving the joystick up and down.

Pick up all 4 flying swords at the beginning of each stage to turn Gurianos' sword RED. If the player is then able to hit an opponent's shield 14 times with his RED SWORD, is armor is momentarily changed to a glowing GOLD color and his opponents can't harm him.

Break the Magic Crystal Balls to replenish Gurianos' armor.

Each opposing warrior has his own personality and way of fighting. Irene is vulnerable when she strikes at the player's chest armor. Zenon is most vulnerable when you trick him and make him laugh. Each opponent has his strengths and weaknesses and it's fun and challenging to the player to learn each of them.
